[Rhodes22-list] Compression Repair and Addition of Compression Post

Tue Feb 24 21:07:27 EST 2009

Rick,
I've been watching the discussions with interest concerning the compression  
posts and the problems people are having. In all the years that I have owned 
my  Rhodes and been a part of this community, I have never before seen any  
discussions around this problem. After careful consideration and a whole lot of  
rum, I'm thinking that you all (southern expression) are doing something to  
these boats that you shouldn't be doing. My first thought is that the shrouds  
and stays are being tightened way to much. I would really appreciate further  
information. And why would anyone need to replace the mast step?

The yard  painting my boat just replaced the mast step.  They are not happy
with  the beautiful compression post I fashioned from an oak full round
supported  by the cross-beam that frames the head sole.

They're thinking of  replacing the post with a truss to the head bulkhead.
This would carry the  load down to the keel and prevent hull deformation when
compression loads  the cross-beam.
